怎么提高石墨模具的寿命呢?辉县市金镶玉石墨模具制品有限公司小编给大家从五个方面说说技巧。

1。石墨模具双色球红蓝走势图的断裂与热压模的夹紧和压降不均匀有关。由于热压烧结工人的经营程度和职业道德相互交融,装货程度差距较大,建议每月定期对工人进行培训,并将模具成本的乘数系数计入工人工资中。此外,模具的断裂损伤也与石墨数据的阻力有关。同时,模具的电阻也表征了数据的石墨化程度,而石墨化程度与导热系数成正比。电阻越低,导热系数越高。温度越快,由于石墨数据强度随温度的升高而增大,1000℃的石墨强度比室温下的石墨强度高20%左右,因此选用电阻低的石墨数据,热压时间短、速度快。石墨模具与刀头接触的强度迅速增大,不易产生破裂现象。同时,缩短了热压烧结时间,节约了烧结成本,减少了氧化时间,降低了氧化损伤率,增加了模具应用数量。
